At West Painting, they get about three calls a day asking for an estimate of the cost for having the interior of a house painted

. To write up an estimate for the cost of a job, they need to know how much paint a job will take. If they average painting 3/4 of a room with 2/5 of a gallon of paint, then they can paint, on average,
rooms per gallon.

A small bar of gold measures 40 mm by 25 mm by 2 mm. One cubic millimeter of gold weighs about 0.0005 ounce. Find the volume in
slamgirl [31]
I'm believing that you have the measurements in the right order, lwh, the Volume would be 5,000. You'd take 40 x 25 x 2= 5,000.

The weight is 2.5 oz. You get this answer by taking the Volume, 5,000, and multiply it by 0.0005 and you get 2.5 ounces.

I hope this helps!

11. Consider rectangle ABCD.
stich3 [128]

Answer:

A'(-24,1), B'(3,1), C'(3,7), D'(-24,7)

Step-by-step explanation:

Rctangle ABCD has vertices at points A(-6,5), B(3,5), C(3,7) and D(-6,7).

The dilation with the center at vertex C and a scale factor of three has the rule

(x,y)\rightarrow (3(x-x_C)+x_C,3(y-y_C)+y_C)

Then

  • C(3,7)\rightarrow C'(3,7);
  • A(-6,5)\rightarrow A'(-24,1);
  • B(3,5)\rightarrow B'(3,1);
  • D(-6,7)\rightarrow D'(-24,7).

The coordinates of the vertices of quadractical JKLM are J(-3,2), K(4,-1), L(2,-5), and M(-5,-2). Find the slope of each side of
UkoKoshka [18]
<span>Right side of the quadrilateral's slope: 
(-1 - (-5))/(4 - 2) = 2 
Left side of the quadrilateral's slope: 
(2 - (-2))/(-3 - (-5)) = 2 
These have the same slope, so they are equal.

Top side of the quadrilateral's slope: 
(-1 - 2)/(4 - (-3)) = -3/7 
Bottom side of the quadrilateral's slope: 
(-2 - (-5))/(-5 - 2) = -3/7 
These also have the same slope so they are also equal.

Because the left and right sides are equal and the top and bottom sides are equal, we can say that the quadrilateral is a parallelogram.</span>
